Its a crap shoot. FedEx over night has been the best for me. Had a 125 lb amp sent to me. FLS dlivered a skid of 250 lb speakers no problem. Contributing factors to damage are poor packing, how many times the item is handled before it arrives and unfortunately luck. It does cost more to ship next day, but it will cut down on man-handling. Alway check the rating of the boxes you ship in. If you ship a 100 lb item in a box rated at 75 lb it may not be covered if damaged.
